If it's an acoustic neuroma, will the symptoms be perceived in both
ears? Can someone give a summary of what an acoustic neuroma is? Is
it a benign or malignant tumor? How much time tends to pass from when
it first causes symptoms till it becomes dangerous? Does it develop
slowly enough in some cases to cause what seems to be ordinary
progressive hearing loss?
Assuming it's not an acoustic neuroma, what other possibilities are
there which could cause such symptoms? The specific symptoms are that
steady tones seem to fade away gradually till they are perceived as
being completely gone, but when the tone is then interrupted for a
fraction of a second, it is perceived as coming back at full loudness.
Also, before it has faded away completely, it seems to change from a
tone to a remote din. In other words, it doesn't fade to a faint tone
before fading away, but rather loses its tonal quality first.
